Summary

Porter County does not require every pet be sterilized, but Sec. 4-12(f) mandates spay or neuter at the owner's expense before the county animal shelter will release an animal on its third or subsequent impoundment redemption within 12 months.

These county ordinances apply to unincorporated areas of Porter County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

An animal that has been previously impounded and is now being redeemed for the third or subsequent redemption within a 12-month period is required to be: (1)Implanted with a microchip at the owner's expense for the purpose of future identification and recovery; and (2)Spayed or neutered by a licensed veterinarian at the owner's expense prior to the county animal shelter relinquishing the animal to the owner. If owner is unable to pay the full costs associated with spaying or neutering the animal, the county animal shelter director may enter into a payment agreement with the owner, or the owner may sign over ownership rights to the county animal shelter.

Full Breakdown

Sec. " Beyond this repeat-offender trigger, the county encourages but does not mandate general sterilization: Sec. 4-15(3), governing shelter adoptions, states "all unaltered dogs or cats shall be surgically sterilized in accord with state law and the county animal control ordinance" as a condition of adopting from the shelter itself. Separately, Sec. 4-9(a) makes sterilization a precondition for a cat to qualify for the county's at-large exemption, and Sec. 4-13 uses sterilization as part of its trap-neuter-return program for feral cats. None of these provisions require sterilization of an animal that has never been impounded or adopted from the shelter.

Violations & Fines

An owner who does not comply with the Sec. 4-12(f) spay/neuter requirement on a third or subsequent redemption within 12 months will not have the animal released; the shelter director may instead require a payment plan or the owner may sign over ownership of the animal to the county animal shelter. Failure to pay outstanding impoundment and redemption fees before compliance also blocks release under Sec. 4-12(b).

Frequently Asked Questions

Does Porter County require all pets to be spayed or neutered?
No blanket mandate exists. Sec. 4-12(f) only requires spay/neuter, at the owner's expense, before the county animal shelter releases an animal on its third or subsequent impoundment redemption within a 12-month period.
What if I can't afford to sterilize my repeatedly impounded pet?
Sec. 4-12(f)(2) allows the shelter director to enter a payment agreement with the owner, or the owner may instead sign over ownership rights to the county animal shelter rather than pay for the procedure.
Do shelter-adopted animals have to be sterilized?
Yes. Sec. 4-15(3) requires that "all unaltered dogs or cats shall be surgically sterilized in accord with state law and the county animal control ordinance" as part of the adoption process.
